    Abstract: The present disclosure relates generally to the use of medical devices for the treatment of vascular conditions. In particular, the present disclosure provides devices and methods for using electrically-induced pressure waves to disrupt vascular blockages. The present disclosure not only provides devices and methods for using electrically-induced pressure waves to disrupt vascular blockages, but the present disclosure also provides devices and method for assisting the guidewire in penetrating an occlusion, devices and method for using a sealable valve in the tip of the balloon catheter to reduce the overall size and diameter of the balloon catheter, thereby allowing the balloon catheter to penetrate smaller size blood vessels and devices. Given the persistence of coronary artery disease (CAD) and peripheral artery disease (PAD), there remains a need for improved therapeutic methods designed not only to reduce vascular blockages in the short term, but also to prevent future complications such as restenosis.

    Abstract: Devices, methods and systems for removing unwanted tissue from within a patient's vasculature system are provided. Specifically, a laser ablation catheter having a tip with an open, arched-shaped cross section is described. The cross section of the tip enhances the catheter's ability to ablate, separate, and/or dilate the various layers within a patient's vasculature, thereby facilitating the removal undesirable lesions and fibrous tissue within a patient's vasculature.

    Abstract: A dilation balloon is wrapped in one or more patterns with a wire or braided material having diamond abrasive or other abrasive material bonded thereto. The wire or braided material is vibrated in one or more ways to enhance the cutting action of the wire abrasive. The wire abrasive may be vibrated using high, low, or even ultrasonic waves transmitted to the wire abrasive via local or remote methods. Alternatively, the dilation balloon may be dilated with a contrast media that exhibits a high absorption to laser light. The contrast material is lased with a laser fiber or fibers inserted into the balloon interior, creating a substantial shockwave that vibrates the balloon and assists in the cracking or abrading of the surrounding plaque in contact with the dilation balloon. The cutting balloon may employ the abrasive coated wires described above or cutting blades.
